CEA-Leti researching on enhancing vehicle driving automation through V2X
Date: 27/10/2023
There is significant digital infrastructure such as GPS, Wi-Fi, 4G/5G wireless networks, and billions of wireless devices in the form of smart phones, automotive electronics and many such ubiquituos networked digital systems all around. It is smarter to leverage fixed as well as mobile digital systems for autonomous driving systems. In today's world most of the people carry a wireless device in the form of mobile phone/smart phone. Self driving automotive can nearly assume the wireless device is an obstacle which it should avoid crashing.
In line with this thinking, semiconductor and electronics focused research organisation CEA-Leti announced a new R&D initiative to contribute to a higher level of vehicle automation and cooperation by expanding the latest developments in vehicular wireless communications that improve reaction time, pedestrian detection and overall vehicle performance. The researchers are CEA-Leti focusing on evaluating and demonstrating connected and cooperative vehicular systems to improve automation and help ensure the safety of vulnerable road users, such as pedestrians, workers and cyclists. CEA-Leti scientists have consolidated the institute's expertise in vehicle-to-everything (V2X) communication technologies and standards after participating in three EU H2020 projects. The H2020 studies included integrating a dedicated simulation flow for system-level evaluation of different short- and long-range radio technologies, such as IEEE802.11.p/bd, C-V2X sidelink or 5G-NR. They also investigated different architecture and infrastructure options, including roadside units, 5G base stations and MEC servers.
“The ultimate goal of our ongoing work is to help our partners in the automotive and related industries understand and adopt the benefits of V2X cooperative communications for improved safety, efficiency and automation performance," said Benoît Denis, research scientist on radio localization and project manager at CEA-Leti.
Denis said that while V2X communication technologies and protocols were initially developed to improve road safety through cooperation, the growing use of autonomous fleets of collaborative robots and drones raises similar research questions and challenges in a variety of complex mobile operating contexts.
“Most important, a simulation tool the team developed was used to measure the actual impact of observed communication network performance in terms of latency, link reliability, coverage and load, on the critical vehicular applications," explained Valérian Mannoni, research scientist on communication protocol and project manager at CEA-Leti. “These include service availability and continuity, level of automation allowed, time to collision and other primary key parameters."
Mannoni said that as a result CEA-Leti also is exploring possible extensions of these H2020 studies in application fields for which standardization is still in its infancy, notably in connection with 6G, which could include cooperative robotics and digital twinning in factories of the future.
